Would be pretty ironic and quite funny that he showed him he´s gonna play THIS

I have remember to use less s-words then (I just edited one of my later messages to replace it with "things"). A friend of mine working for the (Finnish) army once complained he had hard time visiting many forums as the pages would be blocked if there was even one dirty word. I seriously don't get that... Are we kids or something?

One thing though, our employer's antivirus software seems to be very strict, but incoherent, about what pages it considers potentially harmful. For example, it claims that e.g. replacementdocs site is a harmful site, and blocks it. Yet, pirate torrent sites seem to be fine?

Same here. I am quite often in the mode anyway that my work and leisure time are interleaved. I quite often continue work at home after the workday, like today. I read a work email, reply to it, go check some fault report, read a couple of GOG forum messages and write one myself, while in the background I am waiting for some work related processing to finish... Only when I have to do something where I really have to concentrate, I do only that one thing. Then I don't even read my email either (and I get angry calls because I don't reply to them instantly).

Well, it was good enough for my purpose, and free. :)

But not enough for them to send off a recon team to investigate the SLC(sudden loss of contact) with one of the office terminals ;P

About as much could be said for me. I need to cool off my head from all those numbers and parallel lines when I work hard on Acad to finish a .dwg by the end of the shift.

If they want and you use their system the can see everything, probably even your passwords.

What you could do is rather simple:

Bootable OS on an USB Stick with installed games on it.
If you like some risk involved you could get "portable" games that don't require systemfiles and can run from the USB stick
Other than that I suppose you could just ask, as others have already mentioned.

Usually when I get blocked, I just tether my smartphone and read the offending page of posts. It's more of a nuisance. I don't think it's curse words, but the descriptive nature of those curse words. Mostly the ones that keep people from viewing the porn sites.

As far as I remember replacementdocs was hacked and there was malware, that's maybe the reason why it's still on the blacklist. Torrent-sites on the other hand only show links and so don't look riskful to a virus scanner in the first place.

About the topic: Beside the fact that I would not recommend to install/play games on your working system while it seems not allowed, some portable looking games still create files in the AppData folder and take use of the registry. Also you don't know if there is a tracker in the background which logs what programs you run at which time, especially when your employee take a lot of work to remove anything from the system that distracts you from work. .

Edit Yep, I remembered correctly about replacementdocs: http://www.replacementdocs.com/news.php?extend.189

Well what do you know, now I seem to be able to connect to that web site also with my work PC. :) So apparently the virus scanner is smarter than I thought.

I have one: YOU'RE FIRED!

Clean out your desk and turn in your standard-issue assault rifle.

It is fine. We just get Matthew Broderick in to fix things when the computer goes nuts! He could really use the work...

Actually, I think YOU'RE FIRED!

and to the OP - I cant really comment as my boss makes me drink and play games at work all the time.

Where do you work? Playboy Mansion? Can you get me a job there, in ever sense of the term "job".

In the current environment I would only say it is not worth getting fired over games.

On a anecdotal note, from about a year back.
Where I work I am banned from taking in my 3DS because I wanted to download something, so I 'broke' their pitiful excuse for network protection to connect it, using just the 3DS and a paper clip. (The IT department still had no idea how it was done unless they bother to read this).
Anyway they now ban me from taking my 3DS to work, and wanted proof that my tablet could gain access to the internet by itself before they would let me take that back into work.
So instead I installed Worms 2, a chess game and a copy of Pong I made myself in GameMaker onto one of the warehouse machines for use during our lunch hours.
They are hidden in a hidden folder in the Windows directory, and have an invisible shortcut which is placed well away from any 'legit' program shortcuts. No one will ever find it unless I tell them where it is as the folder has one of those stupid $FK34593gd*Be647HE like names.

Anyway apparently what I do is wrong whilst others in upper management are allowed to connect to Facebook when they arrive and spend the entire day playing Farmville.
I have in fact been told to go away by our stock controller because they are busy, but when I wander past her, she is playing Farmville during work hours.
Our IT department is a little over their head with most issues that cannot be fixed by phoning support, so I guess that is only to be expected.

Unless someone in the IT department is a real BOFH then they'd likely only care if you were compromising system/network configuration or security policies. If you have to circumvent any measures they've taken to lock down the system then don't do it, since they'll probably notice that and won't be too pleased. Also, if the game tries to phone home for any reason then they'll likely notice the hits on the company firewall and come asking you questions about it. Aside from that, the far more likely scenario of you getting "caught" is your boss walking by and noticing you playing games instead of working. If you think they'd be cool with that then you probably don't have much to worry about, if not then save your gaming for your own time.

Your post reminds me of "Office Space" and the Tetris 'I'm gonna have to ask you to come back another time' scene.
